What lenses do you own? Do you want to stay with Nikon? Do you want to stay with DX? In Nikon DX I have found the D7500 to have pretty good low light performance at higher ISO. It has the newer sensor. You might consider a lens upgrade and keep the D5600. Either look to a 1.4 or 1.8 lens--or a lens with good VR, or both.
I currently use the Tamron 90mm macro lens. I'd prefer to stay with Nikon since that is the mount the lens was made for. I don't have a preference of sensor format right now.
